Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
A study patient will be considered to have completed Study AG201 at the end of 12 weeks of treatment (ie, Week 12 or End of Study [EOS]).
This definition is based on the timepoint for primary endpoint assessment. A safety follow-up phase of 6 weeks will occur following the Week 12 or End of Study [EOS] visit. |
Se considerará que un paciente del estudio ha completado el estudio AG201 al final de las 12 semanas de tratamiento (es decir, en semana 12 o el final del estudio [FE]).
Esta definición se basa en el momento de la valoración de la variable de evaluación primaria. Después de la visita de la Semana 12 o de la visita de final del estudio tendrá lugar una fase de seguimiento de seguridad de 6 semanas. |
